Course Introduction
Overview of this course and eVOTECH eLearning.

Electrical Safety
Rules and precautions while working with electrical equipment.

Matter, Energy, and Electricity
State the meanings of and the relationship between matter, element, nucleus, compound, molecule, mixture, atom, electron, proton, neutron, energy, valence, valence shell, and ion.

Conductors, Semiconductors, and Insulators
State, in terms of valence, the differences between a conductor, an insulator, and a semiconductor, and list some materials which make the best conductors and insulators

Static Electricity
State the definition of static electricity and explain how static electricity is generated.

Magnetism
State the meanings of retentivity, reluctance, permeability, ferromagnetism, natural magnet, and artificial magnet as used to describe magnetic materials.

Electrical Energy
State, using the water analogy, how a difference of potential (a voltage or an electromotive force) can exist.

Voltage
List six methods for producing a voltage (EMF) and state the operating principles of and the uses for each method.

Electric Current
State the meanings of electron current, random drift, directed drift, and ampere, and indicate the direction that an electric current flows.

Conductance
State the definitions of and the terms and symbols for resistance and conductance, and how the temperature, contents, length and crosssectional area of a conductor affect its resistance and conductance values.

Resistance
List the physical and operating characteristics of and the symbols, ratings, and uses for various types of resistors; use the color code to identify resistor values.

Batteries
Define a battery, and describe general maintenance procedures for batteries including the use of the hydrometer, battery capacity, and rating and battery charging.

Schematic Diagrams
Identify the term schematic diagram and identify the components in a circuit from a simple schematic diagram.

Ohm's Law
State the equation for Ohm’s law and describe the effects on current caused by changes in a circuit.

Watt's law
Given simple graphs of current versus power and voltage versus power, determine the value of circuit power for a given current and voltage.

Series and Parallel Circuits
Compute circuit and component power in series, parallel, and combination circuits
